Hi, I'm Sage

I'm a 14-year-old singer-songwriter, fantasy author, and full-time adventurer living on a sailboat in the Caribbean Sea.

I was born in Southern California and grew up between California, Abu Dhabi, Oregon and Cambridge — but for the past few years my home has been the ocean. My family and I live aboard a catamaran and sail from island to island, which means my backyard is the Caribbean Sea and my commute to school is approximately zero minutes.

I'm homeschooled, which gives me the time to do the things I love most: write fantasy novels, write and perform original music, free dive, bake (especially cookies and beef and bean chili), and hang out with my friends wherever we happen to be anchored.

The Music

I wrote my first song at eight years old, but it wasn't until I discovered Taylor Swift at eleven that writing really clicked for me. From there I was hooked — and I haven't stopped since.

I write and perform original songs, mostly inspired by real things that happen to me or the people around me. I play acoustic guitar and piano, and I work closely with my songwriting teacher Paulina Jayne.

You can find all my music on Instagram at @songs.by.sage. I post original songs and love connecting with people who listen.

The Books

I've always loved fantasy — magic, adventure, battles, and worlds where anything is possible. I wrote my first book at eleven and spent two years editing it before publishing it at thirteen.

That first book, Guardians of the Secret Isles: The Emerald Jaguar, is a middle grade fantasy adventure published in June 2025. It's the beginning of a five-book series, and there are more stories already in progress.

Writing taught me that creativity is powerful, but persistence is what turns imagination into reality. I'm proof that you don't have to wait to grow up to tell your story.

The Boat Life

Living on a sailboat is as wild as it sounds. We anchor in new places, meet cruising families from all over the world, and experience things most people only read about.

I do Aerial Silks from the mast of the boat. I free dive in the clearest water you've ever seen. I watch sunsets from the cockpit with my guitar. And I write — always write — wherever we are.

The sailing life gives me endless material. Every island is a new story. Every anchorage is a new chapter. I wouldn't trade it for anything.
